# .SYNOPSIS
# This CmdLet compiles the simulation libraries from Altera.
# 
# .DESCRIPTION
# This CmdLet:
#   (1) creates a subdirectory in the current working directory
#   (2) compiles all Altera Quartus-II simulation libraries and packages
#       o Altera standard libraries: lpm, sgate, altera, altera_mf, altera_lnsim
#       o Altera device libraries:
#         - arriaii, arriaii_pcie_hip, arriaiigz
#         - arriav, arriavgz, arriavgz_pcie_hip
#         - cycloneiv, cycloneiv_pcie_hip, cycloneive
#         - cyclonev
#         - max, maxii, maxv
#         - stratixiv, stratixiv_pcie_hip
#         - stratixv, stratixv_pcie_hip
#         - fiftyfivenm, twentynm
